FIG. 4A is a flowchart of an example of a process, according to various embodiments. - In
operation 410, theelectronic device 101 may acquire an electric signal from the touch panel. For example, the touch panel may include a plurality of electrodes. The plurality of electrodes may output electric signals by a change in an electric field around the plurality of electrodes, and theelectronic device 101 may acquire the electric signals from the plurality of electrodes of the touch panel. - According to various embodiments, the touch panel may acquire electric signals in two situations. In the first situation, a first electrode of the touch panel is configured as a transmission electrode and a second electrode is configured as a reception electrode and thus the first electronic device transmits an electric field. The second electrode corresponding to the reception electrode may output an electric signal by the electric field from the first electrode. In this case, the second electrode may output, for example, an electric signal having a voltage of a. For example, when a user's finger is located in proximity to the second electronic device, the finger may absorb some of the electric field from the first electrode. The second electrode may output, for example, an electric signal having a voltage of b by the remaining electric field except for some of the electric field absorbed into the finger. The
electronic device 101 may determine a touch position according to a difference between the electric signals. - In the second situation, electrodes of the touch panel may output electric signals by an electric field from a user's body. In the user's body, a zero potential line having a potential of 0 may be generated while crossing the heart, and a potential having a positive value may be formed on one side of the zero potential line and a potential having a negative value may be formed on the other side of the zero potential line. Accordingly, the potential, that is, the electric field may be formed on the end of the user's body, for example, a finger. The electrodes of the touch panel of the
electronic device 101 may output electric signals by the electric field formed on the finger. - As described above, the electrodes of the touch panel may output electric signals by the electric field of the transmission electrode or the electric field of the user's body. The
electronic device 101 according to the various embodiments may acquire electric signals output from the touch panel through the aforementioned various methods. - In
operation 420, theelectronic device 101 may detect whether an operation mode is an ECG sensing mode. According to an embodiment, theelectronic device 101 may determine the operation mode based on a user's input. For example, theelectronic device 101 may determine the operation mode to be the ECG sensing mode based on the user's input. Alternatively, theelectronic device 101 may determine the operation mode to be a touch position determination mode based on a user's input. - According to another embodiment, the
electronic device 101 may determine the operation mode by itself based on at least one of a touch time and a touch pressure of the detected touch. For example, when at least one of the touch time and the touch pressure of the touch is equal to or smaller than a threshold, theelectronic device 101 may determine the operation mode to be the touch position determination mode. Alternatively, when at least one of the touch time and the touch pressure of the touch is larger than the threshold, theelectronic device 101 may determine the operation mode to be the ECG sensing mode. - According to another embodiment, when the touch pressure is larger than a preset threshold, the
electronic device 101 may determine the operation mode to be the ECG sensing mode. Theelectronic device 101 may determine the ECG sensing mode by using both the touch time and the touch pressure. - According to another embodiment, when a potential difference of electric signals from a plurality of detected touches is equal to or smaller than a threshold, the
electronic device 101 may determine the operation mode to be the touch position determination mode. Alternatively, when the potential difference of the electric signals from the plurality of detected touches is larger than or equal to the threshold, theelectronic device 101 may determine the operation mode to be the ECG sensing mode. - When the operation mode is the ECG sensing mode, the
electronic device 101 may sense the ECG by using the electric signals from the touch panel inoperation 430. For example, theelectronic device 101 may acquire electric signals from at least two areas of the touch panel. For example, theelectronic device 101 may acquire a first electric signal from a first area of the touch panel and acquire a second electric signal from a second area of the touch panel. The first area is an area corresponding to a first touch and may correspond to one or more channels of the touch panel, and the second area is an area corresponding to a second touch and may correspond to one or more channels of the touch panel. Theelectronic device 101 may sense the ECG based on a potential difference of the first electric signal and the second electric signal. As described above, both hands of the user's body may have potentials of different poles. Accordingly, the first electric signal output by the potential of one hand of the user and the second electric signal output by the potential of the other hand of the user may be different from each other. Further, each of the first electric signal and the second electric signal may vary depending on time according to activities of the heart. Theelectronic device 101 may sense the ECG corresponding to the activities of the heart based on the difference between the first electric signal and the second electric signal. - When the operation mode is the touch position determination mode, the
electronic device 101 may determine a touch position on the touch panel by using the electric signals from the touch panel inoperation 440. As described above, theelectronic device 101 may determine the touch position based on the electric signal from each electrode, which will be described with reference toFIGS. 5A to 5E . - In the above description, the
electronic device 101 may first determine the operation mode, and then sense the ECG or determine the touch position by using the electric signals according to the determined operation mode. When theelectronic device 101 senses the ECG, theelectronic device 101 may release a connection between a circuit for determining the touch position, for example, a driver for scanning and the touch panel. When theelectronic device 101 may determine the touch position, theelectronic device 101 may release a connection between a circuit for sensing the ECG and the touch panel. -
FIG. 4B is a flowchart of an example of a process, according to various embodiments. As described above, when theelectronic device 101 ofFIG. 4A may sense the ECG or determine the touch position, theelectronic device 101 ofFIG. 4B may simultaneously perform the sensing of the ECG and the determination of the touch position. - In
operation 410, theelectronic device 101 may acquire electric signals from the touch panel. - In
operation 450, theelectronic device 101 may sense an ECG by using the electric signals. Inoperation 460, theelectronic device 101 may sense the ECG and determine a touch position by using the electric signals at the same time. - The
electronic device 101 may sense the ECG by using a component of a first frequency band among electric signals generated from the touch panel. Theelectronic device 101 may determine the touch position by using a component of a second frequency band among the electric signals generated from the touch panel. For example, the ECG may be a relatively low frequency band, and an electric field generated from a transmission electrode of the touch panel may be a relatively high frequency band. Accordingly, theelectronic device 101 may sense the ECG by using the component of the first frequency band which is the relatively low frequency band of the electric signal. Further, theelectronic device 101 may determine the touch position by using the component of the second frequency band which is the relatively high frequency band of the electric signal. Theelectronic device 101 may use the frequency band through a filter, which will be described with reference toFIG. 6C . - According to the above description, the
electronic device 101 may sense the ECG and use the sensed ECG for an authentication process. Theelectronic device 101 may perform an application execution operation including the authentication process according to an authentication result.
